No. 10/744,748, filed Dec. 23, 2003, entitled “Sealing StripComposition”, which is currently pending, which is a continuation inpart of U.S. patent application Ser.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a sealing strip used in the construction ofinsulating, double pane structures. More particularly, the inventionrelates to a sealing strip composition comprised of an adhesion promotercompound of at least two components, a polymeric base material(s), across linking agent(s), fillers, molecular sieves, plasticizers andtackifier.

2. Description of the Prior Art

Various sealing structures have been developed for use in thefabrication of insulating glass structures. These sealing structures aregenerally positioned between adjacent panes and act to maintain thepanes in a spaced relationship. The sealing structure must also preventthe passage of undesirable materials within the space defined betweenthe adjacent panels. The passage of, for example, water vapor, leads tothe formation of undesirable condensation between the panes. Once suchcondensation has made its way within the space between the panes, thedouble pane becomes unuseable.

With this in mind, a sealing structure must be optimized to maintain thespacing between the panes, adhere to the surface of the panes so as tocreate a barrier to the passage of vapor between the sealing structureand the pane, and be substantially impermeable to vapor through thesealing structure itself. A variety of sealing structures are known toexist, but each is known to possess shortcomings requiring modificationof the base sealing material through the inclusion of various structuraladditives such as spacers and vapor barriers.

For example, and with reference to U.S. Pat. No. 5,855,972 to Konrad H.Kaeding, a sealant strip for use in the fabrication of insulating glassis disclosed. In the '972 patent, Kaeding provides examples of using adeformable sealant strip to manufacture insulating glass for use inwindow systems. Although he makes some strides in overcoming previousdeficiencies in analogous systems, he fails to completely resolve theissues of simplicity, resistance to compression, good adhesion and easeof manufacture. He gives many examples of “grafting polymers onto thebackbone of the Exxon Exxpro polymers”, but he does not obtain thedesired product without further manipulation. However, Kaeding was notable to resolve all issues and obtain the optimum synergy.

Kaeding claims to provide excellent adhesion, but offers no data. Heclaims to have a system that is resistant to compression, but uses“staples” within the sealant strip to maintain the desired dimensionsand to prevent compression. In addition, he discusses the use of plasticand/or metal vapor barriers to prevent the ingress of water and otherexternal materials into the cavity of the insulating glass unit. He alsouses several complex “curing” systems.

All these issues are overcome in accordance with the present inventionby the simple use of polymers and a dual curing/adhesion promotingsystem. The present invention overcomes these deficiencies with asimplified cross-linking system to prevent compression that occurs overa period of time and a grafting of adhesion promoters, preferably of thesilane type, onto the backbone of the Exxon polymers.

Also, in one embodiment of the present invention the present sealingsystem takes advantage of using a liquid adhesion promoter, such as asilane compound, and a liquid cross-linking agent, both of whichfacilitate the ease of incorporating these materials into the elastomermatrix to provide a far more homogeneous product.

FIG. 2 is a cross sectional view of a glass double pane structure inaccordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The detailed embodiments of the present invention are disclosed herein.It should be understood, however, that the disclosed embodiments aremerely exemplary of the invention, which may be embodied in variousforms. Therefore, the details disclosed herein are not to be interpretedas limited, but merely as the basis for the claims and as a basis forteaching one skilled in the art how to make and/or use the invention.

With reference to FIGS. 1 and 2, an insulating glass structure 1incorporating a sealing strip 14 providing separation of adjacent panes10, 12 and sealing of the space therebetween is shown. As those skilledin the art will readily appreciate, the inventive concepts of thepresent sealing strip 14 may be applied in various manners withoutdeparting from the spirit of the present invention. For example, it iscontemplated that the present sealing strip may be used in conjunctionwith other materials, for example, various types of glass, including,clear float glass, annealed glass, tempered glass, solar glass, tintedglass, Low-E glass, acrylic sheets and polycarbonate sheets.

In accordance with the present invention, the sealing strip 14 isapplied in the construction of a double pane glass structure. Theinsulating glass structure, therefore, generally includes a first pane10 and a second pane 12 separated by a sealing strip 14 positionedbetween the first pane 10 and the second pane 12. The use of a sealingstrip 14 in accordance with the present invention provides improvedadhesion, vapor barrier characteristics and compression resistantcharacteristics. As a result, the present sealing strip 14 may bereadily formed and applied without the need for supplemental vaporbarriers and spacers commonly found in prior art sealing devices.

Vapor barriers are generally used in prior art devices when the sealantsystem does not have a good moisture vapor transmission rate, that is,it allows moisture to travel through the sealant at a rate that wouldallow too much moisture into the air space between the panes causingcondensation between the panes. These vapor barriers may also be used asmechanical spacers to maintain a certain thickness of airspace in thewindow. The present sealing strip offers excellent moisture vaportransmission rates. In addition, the rheology of the composition is suchthat due to controlled internal cross linking of the materials, thesealing strip will withstand attempts for compression and it willmaintain the air space with no additional help from a supplemental vaporbarrier spacer. The theoretical cross linking agent in accordance with apreferred embodiment of the present invention is disclosed below.

The preferred material prepared by the use of an adhesion promoter andthe cross linking agent provides the unique property which allows onlyminimal compression set when put under constant stress due to the crosslinking of the material. If one uses too great a quantity of eithermaterial, one can get less than 0.001 inch of compression set. However,this makes the material very tough and almost impossible to handle. Inaddition, when such material is used to manufacture an insulating glassunit the adhesion to glass is reduced. It is only through the uniquecombination of the correct amount of adhesion promoter, such assilane(s), and cross linking agents that one is capable of obtaining amaterial which is handable, gives good adhesion and resists compressionset. Indeed, previously unknown dramatic synergistic effects between twoor more adhesion promoters results in substantial enhancement ofadhesive strength as illustrated in the examples below.

In addition, this reinforcing can be further enhanced by the use ofappropriate fillers as seen in the formulation. This allows theformulator a third alternate in controlling the resistance tocompression.

When put under a constant pressure of 30 pounds per square inch forweeks at a time, the compression set is less than 0.030 inch.

The sealing strip in accordance with the present invention is generallycomprised of an adhesion promoter composed of at least two components, apolymeric base material(s), a cross linking agent(s), plasticizers (oroils or diluents), fillers, molecular sieves and tackifier. The use of across linking agent and adhesion promoter in combination with tackifierresults in a sealing strip offering improved compression and adhesioncharacteristics. This allows the sealing strip to be used in thefabrication of insulating glass structures without the need foradditional spacers and vapor barriers.

In accordance with a preferred embodiment of the present invention, theadhesion promoter(s) comprises approximately 0.25-7.00% by weight, andpreferably approximately 0.50-2.50% by weight, of the sealing stripcomposition. While the use of a single component adhesion promoterproduces a useful product, the present invention is greatly improvedthrough implementation of two or more components. The components of theadhesion promoter are chosen from the group consisting ofacetoxysilanes, alkoxysilanes, epoxysilanes, silane-esters,methacryloxysilanes, organopolysiloxanes, organosilanes, organosilanols,vinylsilanes, organoaminosilanes, polysulfidesilanes, mercaptosilanes,ureidosilanes, or a combination thereof. Specific examples includebis-(triethoxysilylpropyl)disulfide,bis-(triethoxysilylpropyl)tetrasulfide,gamma-aminopropyltriethoxysilane,gamma-glycidoxy-propyltrimethoxysilane,gamma-mercaptopropyltriethoxysilane,gamma-mercaptopropyltrimethoxysilane,gamma-methacryloxypropyltriethoxysilane,gamma-methacryloxypropyltrimethoxysilane,gamma-ureidopropylltrimethoxysilane, methyltris(isopropenoxy)silane,N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilane,(N,N-Dimethyl-3-aminopropyl)silane, polydimethylsiloxane,vinyltriethoxysilane, tris-(3-(Trimethoxysilyl)propyl) isocyanurate, ora combination thereof Organoaminosilanes have proven to be preferredcomponents of the adhesion promoter for use in accordance with thepresent invention. As discussed below with reference to the experimentalresults presented, utilizing more than a single component producesgreater adhesion properties than would otherwise be obtained. Inaccordance with a preferred embodiment, the present invention isimplemented using two different silane components as the adhesionpromoter. Use of N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilaneas the first component and gamma-mercaptopropyltrimethoxysilane as thesecond component has resulted in particularly desirable experimentalresults as discussed below.

The polymeric base material comprises greater than approximately 10%,preferably approximately 15-40%, and most preferably approximately15-25%, by weight of the sealing strip composition. The polymeric basematerial is composed of compounds comprisingpolyisobutylene/polyisoprene copolymers (e.g., Exxon Butyl),polyisobutylene polymers (e.g. Exxon Vistanex), brominated olefinpolymers (e.g., Exxon Exxpro) and petroleum hydrocarbon oil.

The cross linking agent comprises approximately 0.25-5.00% by weight,and preferably, approximately 0.50-2.50% by weight, of the sealing stripcomposition. The cross linking agent is chosen from the group consistingof divalent metal oxides, divalent salts of organic fatty acids, organicfatty acids, zinc oxide, zinc stearate, stearic acid, zinc octoate(solution and/or solid), tin octoate and calcium stearate in anappropriate form (e.g., liquid or powder).

Where zinc oxide is used it usually needs accelerators such as sulfurcompounds and complex vulcanization systems. While specific acceleratorsare disclosed above in accordance with a preferred embodiment of thepresent invention, there are many other known accelerator systems whichmay be used in accordance with the present invention. The salts ofcalcium, tin and zinc used in accordance with the present invention alsorequire accelerator systems.

In accordance with a preferred embodiment of the present invention, andas discussed below with reference to the various examples presented,zinc octoate solution is a preferred cross linking agent for use inaccordance with the present invention. In addition, it has been foundthat approximately a 17-19% zinc octoate solution works better than 100%solid zinc octoate in accordance with preferred embodiments of thepresent invention. While the use of accelerators is described above withreference to a preferred embodiment of the present invention, thoseskilled in the art will appreciate that the present invention may bepracticed without the use of accelerators.

As briefly mention above, the tackifier forms less than 10% by weight ofthe sealing strip composition. The tackifier is chosen from the groupconsisting of organic monomers, oligomers and polymers, hydrogenated C5and C9 resins, C5 hydrogenated resins, polyterpene resins,pentaerythritol esters of hydrogenated wood resins, phenolic polyterpeneresins, alpha pinene resins, dipentene resins, hydrogenated C5 esters,cycloalkene resins, phenol-aldehyde resins, rosin acids and esters,dipentene resins, petroleum hydrocarbon resins, and alkyl aromatichydrocarbon resins. Preferred tackifiers include pentaerythritol estersof hydrogenated wood rosin and hydrogenated C5 hydrocarbons. The C5hydrogenated hydrocarbon resin may be used alone or in combination withthe pentaerythritol hydrogenated esters. These tackifiers can be usedindividually or in combination and can also be used as is or with adiluent, hydrocarbon oil or plasticizer. In accordance with a preferredembodiment of the present invention, and as discussed below withreference to the various examples presented, C5 hydrogenated resins area preferred tackifier for use in accordance with the present invention.

In accordance with variations on the composition described above, it hasbeen found that the replacement of molecular sieves with talc, or otherinert fillers, results in a class of compounds generally referred to ashot melt adhesives. Such adhesive may also be used as an insulatingglass sealant in a traditional aluminum spacer bar system with the samepositional results described above. As to the other components of such ahot melt adhesive, the tackifier would remain substantially as with thesealing strip composition discussed above. In addition, the tackifierwill be kept to less than 10% as disclosed above with regard to thesealing strip composition.

In forming an insulating glass unit, it is contemplated that the hotmelt adhesive would be applied to a metallic spacer at approximately250° F.-300° F. Once assembled, it is contemplated that the hot meltadhesive will provide adhesion properties and moisture vaportransmission rates substantially similar to those offered by the sealingstrip composition discussed above. The hot melt adhesive will alsoresist compression (but since it is proposed for use with a spacer thisis not a critical issue).

EXAMPLES

The sealing strip composition is formed in the following manner:

Equipment

The equipment is generally referred to as a double arm horizontal sigmamixer. It can have variable speed and needs an external source of heatto control the temperature. It uses a jacket so hot water, steam or coldwater can be run through the jacket to control the internal temperature.It can be vacuum rated but it is not necessary.

Procedure

The following is a general procedure. The times and temperatures canvary somewhat depending on the size of the batch and the mixer used. Asan example, it will take somewhat longer per addition for largerbatches. If the temperature is lower than normal it will take longer tomix in. None of these are deleterious to the final product.

All ingredients are weighed out beforehand except the molecular sievesand the organo silane. They are weighed out just before use (otherwiseboth materials may absorb moisture from the atmosphere). The mixer isheated to approximately 225-250 degrees Fahrenheit (F.), the mixer isturned on and the masterbatch is added over a 10 minute period (thetemperature is maintained between 225-250 degrees F. either by the useof the external heating mechanism or by heat of mixing when eachingredient is added).

The tackifiers are added one by one over a 5-15 minute period. These arepreferably solid pellet or flake type materials which will melt in themix at these temperatures. Mixing is continued until all tackifiers aremelted and homogeneous. The hydrocarbon oil and filler are addedalternately while maintaining a mix that is neither too thick and dry ortoo moist and wet. This can take 15-30 minutes and mixing is continuedfor 5-15 minutes after all the material is added. At this point themolecular sieves are added over 5-15 minutes and mixing is continued foran additional 15 minutes. The molecular sieves are white in color incomparison to the black material in the mixer so one can identify whenthe material is adequately mixed.

The temperature is taken periodically either by a temperature probebuilt into the mixer or by turning the mixer off after taking thetemperature with an external thermometer.

After the molecular sieves are added, the material is cooled to 200degrees F. before the silane and zinc octoate are added. After thesilane and zinc octoate are added, it is mixed 30 minutes, the mixingblades are stopped and the material is removed.

Lap Shear Adhesion/Durometer Readings

Extensive studies of the adhesion of products manufactured in accordancewith the present invention have been carried out by the Lap ShearMethod, ASTM C-961 87 (reapproved 1992). As a reference point, severalcompetitive butyl based sealant strips and hot melt products were testedfrom the marketplace and results were obtained in the range of 12-20pounds per square inch (psi). Durometer readings are a way to measurethe relative internal strength and resistance to compression. With theproper formulation, the adhesion could be optimized and maximized whileobtaining a handable material that still had flexibility but did notflow or take a compression set.

The primary method for optimizing the adhesion properties is theinclusion of more than one component in the adhesion promoter. Synergybetween the components dramatically affects the chemical composition ofthe present invention resulting in an increase in adhesion properties.Secondarily, chemical properties may be optimized by altering theconcentrations of the adhesion promoter and the cross linking agent,controlling the resistance to compression. In one example, theconcentration selected for zinc octoate allows for the optimization ofthe cross-linking concentration and the selected concentration of silanemaximizes the adhesion. Thus we have been able to obtain adhesion valuesbetween 30-80 psi and can control the adhesion in the desired range byemploying the method in accordance with the present invention. Inaddition, because of the unique chemistry of the polymeric material(s)and the zinc octoate cross linking agent, the adhesive strength willimprove with time.

The following examples serve to indicate the advantageous increase inadhesion when using more than one component in the adhesion promoter.These examples are intended to illustrate the invention without,however, limiting the scope thereof

PREPATATION EXAMPLES Preparation Example 1

A product was prepared according to the present invention utilizing asingle silane component in the adhesion promoter. Following heating of amixer, a masterbatch was added over a 10 minute period as describedabove. The masterbatch contained 8.21% by weight of Exxpro 3433 providedby ExxonMobil as the polymeric base material, 8.21% Vistanex MM L-80provided by ExxonMobil, 6.11% Indopol H-300 Polybutene oil, and 18.21%Carbon Black N-330. The tackifiers, specifically 4.60% of Pentalyn G and2.30% of Pentalyn H, both provided by Hercules, 0.73% Acetylene Black,and 8.48% Escorez 1315, provided by Exxon, were then added over a 5-15minute period. Sunpar 2280 oil obtained from Sunoco was then added inthe amount of 14.12% as the hydrocarbon oil alternately with 16.81% ofthe inert filler, Mistron Vapor R Talc provided by Luzenac, over 15 to30 minutes. Following an additional 5-15 minutes of mixing, 7.27% ofMolecular Sieve 3A and 2.52% of Molecular Sieve 13X, provided by UOP,were added in 5-15 minutes. The resultant material was then cooled to200 degrees F. Upon reaching the desired temperature, 1.22% of the crosslinking agent, Octoate Z (17-19%) provided by Vanderbilt, and 1.22% ofthe adhesion promoter, Silane A1120 (N(beta-aminoethyl)gamma-aminopropyltrimethoxy-silane), were added and mixed for 30minutes. Studies of the final product seven days after creation, carriedout by the Lap Shear Method, indicated an adhesion strength of 24.39 psi(pounds per square inch).

Preparation Example 2

A second product was prepared using a single silane component as theadhesion promoter. As in the example above, 40.74% by weight ofmasterbatch containing Exxpro 8433, Vistanex M M L-80, Indopol H-300Polybutene oil, and Carbon Black N-330 was added to a heated mixer overa 10 minute period. Pentalyn G in the amount of 4.60%, 2.30% of PentalynH, 0.73% Acetylene Black, and 8.48% Escorez 1315 were then added over a5-15 minute period. Sunpar 2280 oil in the amount of 14.12% was thenadded alternately with 16.81% of Mistron Vapor R Talc over 15 to 30minutes. Following 5 to 15 minutes of mixing, 7.27% of Molecular Sieve3A and 2.52% Molecular Sieve 13X were added over a 5 to 15 minuteperiod. Upon cooling, 1.22% Octoate Z (17-19%) and 1.22% Silane A-189(gamma-mercaptopropyltrimethoxy-silane) were added and mixed for 30minutes. Use of the Lap Shear Method after aging seven days indicated anadhesion strength of 13.42 psi for the product.

Preparation Example 3

A third single silane product was prepared in the manner of the firsttwo experiments. For this experiment 1.22% by weight Silane Y11597(tris-(3-Trimethoxysilyl)propyl) isocyanurate) was added as the adhesionpromoter. Use of the Lap Shear Method indicated an adhesion strength of12.69 psi for the final product after seven days of aging.

Preparation Example 4

A fourth experiment was conducted in the manner of the first twoexperiments. However, for this final experiment a combination of 0.61%by weight Silane A1120 and 0.61% Silane A189 were added and mixed as acombination of silanes representing a combination of adhesion promoters.Studies of the final product after seven days of aging, carried out bythe Lap Shear Method, indicated an adhesion strength of 42.88 psi. Incomparing the adhesion strength of the product to that of the productsof the first three experiments, the results indicate that a combinationof components, particularly silanes, improved upon the adhesionstrengths obtained through use of a single component.

Preparation Example 5

A fifth experiment was conducted in the same manner of the previousexperiments. In this final experiment a combination of 0.72% by weightSilane A1120, 0.25% Silane A189, and 0.25% Silane Y11597 were added andmixed as a combination of silanes representing a combination of adhesionpromoters. The final product indicated an adhesion strength of 47.62 psiusing carried out the Lap Shear Method after seven days of aging. Incomparing the adhesion strength of the product to that of the productsof the previous experiments, the results support those of the fourthexample indicating that a combination of components, particularlysilanes, improved upon the adhesion strengths obtained through use of asingle component.
